I maintain that it is 100% clear that we need limited-scope addressing, and since we will never have a precise definition of a "site", we'd better not waste our time trying to define "site local" precisely. > > Let's figure out what we really need, and _then_ argue about > the specifics of where to put the address space. > > Did anyone want to comment on Tony's requirements document > and/or propose an alternative set of requirements? I think we should take that draft as good enough, and discuss Bob's proposal as a solution to those requirements.
